DC SPD 1500V 3 Pole | Solar Surge Protector

DC SPD 1500V is built for high-voltage solar strings, combiner boxes, and inverter DC input protection. This 3 pole version is listed at Rs.8,600 on CNC Electric Pakistan. If you are building a 1500V solar plant, this is the class of protector used to divert lightning and switching surges before they punch through inverter electronics, monitoring gear, or DC distribution equipment.

Key Features

• 1500V DC surge protection for photovoltaic systems
• 3 pole format for higher-voltage solar DC layouts
• Nominal discharge current In 20kA
• Maximum discharge current Imax 40kA
• Modular pluggable design for easier replacement
• Green / red status window for quick visual inspection
• Made for PV combiner boxes and DC distribution cabinets

Product Range and Price

Applications

This DC SPD belongs on the DC side of high-voltage solar systems where lightning exposure, long cable runs, and switching events can hit the inverter or combiner box hard. It suits utility-scale solar, large rooftop plants, PV combiner boxes, DC distribution cabinets, and inverter input protection. If the project is still at 600V or 1000V DC, use the lower-voltage DC SPD instead of overspending on a 1500V unit.

How to Choose the Right DC SPD

DC SPD vs Alternatives

What This Product Does NOT Protect Against

This product does not replace a DC breaker, DC isolator, proper earthing system, or correct cable routing. It will not fix poor bonding, bad grounding, wrong voltage selection, or a badly designed combiner box. It is there to clamp and divert surge energy. It is not the only protective device in the system.

Installation Guide

1. Install the SPD in the PV combiner box or DC distribution cabinet as close as practical to the equipment being protected.
2. Keep the earth path short and direct. Long earth runs weaken surge performance.
3. Match the SPD voltage class to the actual DC system voltage. Do not oversimplify 1000V and 1500V selection.
4. Check the status window during maintenance. Replace the module if the indicator shows fault.
